ix-docs

name	ix-docs
description	Generate narrative-first, importance-weighted documentation for a repo, system, or subsystem with a selective reference layer. Use --full for deeper module/class/method coverage.
metadata	{"openclaw":{"requires":{"bins":["ix"]}}}

Run command -v ix to verify ix is on PATH. Never use tilde paths (~/...) or absolute paths — always invoke ix directly via PATH. If not found, stop and say so.

Goal

Produce documentation that helps a new engineer understand the system quickly and gives an LLM strong architectural context without drowning it in low-value detail.

Write like real engineering documentation for a framework or subsystem:

• teach the system
• explain how it works
• show where the important parts live
• surface risks and fragile boundaries
• point the reader to the next files or symbols to inspect

Never write a raw report dump.

---

Core model

Every ix-docs run produces two layers:

1. Narrative layer (always first)

   • human-readable explanation
   • onboarding-focused
   • architecture, flow, usage, risks, navigation guidance

2. Reference layer (always present, but selective)

   • compressed summaries of important modules, classes, and services
   • short, structured, high-signal entries
   • no code dumping

Mode behavior

• ix-docs <target>: narrative-heavy by default, with a minimal selective reference appendix
• ix-docs <target> --full: deeper coverage for important components, still importance-weighted

Style behavior

• --style narrative (default): prose-first narrative sections; reference layer stays compact
• --style reference: tighter, docs-site style structure; narrative stays brief but is not removed
• --style hybrid: full narrative plus fuller selective reference; best match for --full

---

Flags

Fragment	Variable	Default
first non-flag token	TARGET	required
--full	FULL=true	false
`--style narrative	reference	hybrid`
--split	SPLIT=true	false
--single-doc	SINGLE=true	false
--out <path>	OUT_PATH	auto-detect

Output rules

• --single-doc forces one Markdown file
• --split produces a directory with index.md plus per-system or per-subsystem docs
• if neither is set and FULL=true on a repo with more than 10 subsystems, auto-enable SPLIT=true
• --single-doc overrides auto-splitting

Output path auto-detection

1. docs/ exists at workspace root → docs/<target-name>.md or docs/<target-name>/
2. doc/ exists → doc/<target-name>.md or doc/<target-name>/
3. otherwise → <target-name>.md or <target-name>/ at workspace root

If FULL=true, tell the user the planned mode, output path, and whether splitting was auto-enabled before generating the docs.

---

Non-negotiable rules

1. Graph first

   • Start with ix subsystems, ix overview, ix rank, ix explain
   • Use ix read only after graph data leaves an important behavior unclear

2. Importance-weighted expansion

   • Expand detail by centrality, risk, coupling, orchestration role, and user focus
   • Never treat all modules equally

3. Selective low-level detail

   • Default mode: module and class summaries only for important parts
   • Full mode: method summaries only for key classes or services

4. No raw dumps

   • Never output raw command output
   • Never paste command logs
   • Never dump full file inventories, all callers, or all methods

5. No redundancy

   • Group repeated patterns
   • If several modules have the same role, summarize the pattern once
   • If an entity appears in multiple rankings, explain it once and cross-reference

6. Code reads are rare

   • Default mode: at most 2 ix read calls total
   • Full mode: at most 5 ix read calls total
   • Symbol-level only; never read whole files for this skill

---

Coverage policy

Use the following ranking factors to decide what gets expanded:

1. Centrality: ix rank, caller count, dependent count
2. Risk: ix impact
3. Coupling: cross-system or cross-subsystem relationships
4. Orchestration role: coordinators, entry points, workflow managers from ix explain
5. User focus: the exact target and its immediate neighborhood

Always include

• top-level architecture
• all major subsystems in scope
• the most important modules or services

Sometimes include

• important files
• key classes or services
• notable boundary functions or entry points

Only in --full

• selective method summaries for the most important classes or services
• expanded per-subsystem module coverage

Never

• exhaustive inventories
• equal treatment for every module
• long method lists

Expansion budgets

Default mode

• repo or large system: cover all major subsystems, expand the top 3-5 most important ones, reference 5-8 key components total
• subsystem or module: expand the target fully, reference the top 5-8 entities in scope
• symbol or small component: focus on the target, its immediate collaborators, and the surrounding subsystem

Full mode

• repo or large system: cover all major systems, expand the top 5-8 by importance, create short stubs for lower-ranked ones when split output is large
• subsystem or module: expand the top 8-12 entities, add method summaries for the top 3-5 classes or services only

When a repo is very large, prefer:

• full docs for the highest-ranked systems
• short overview stubs for the lower-ranked remainder

---

Command strategy

Do not run every command mechanically. Reuse earlier results and stop when additional depth would not materially improve the documentation.

Phase 1 — Scope

Always start with:

timeout 60s ix stats --format llm
timeout 60s ix subsystems --format llm
timeout 60s ix subsystems --list --format llm

If TARGET is not obviously the whole repo:

timeout 60s ix locate "$TARGET" --limit 5 --format llm

Resolve whether the target is:

• repo
• top-level system
• subsystem
• module or file
• class, service, or symbol

If ambiguous, resolve it before proceeding.

Phase 2 — Architecture

Use the graph to identify systems, subsystem boundaries, and the most important modules.

Common commands:

timeout 60s ix overview "$TARGET" --format llm
timeout 60s ix rank --by dependents --kind class --top 10 --exclude-path test --format llm
timeout 60s ix rank --by callers   --kind function --top 10 --exclude-path test --format llm

If TARGET is the whole repo, skip ix overview "$TARGET" and rely on the pre-run subsystem data plus the rank results.

Additional commands by scope:

For repo or system targets:

timeout 60s ix subsystems "$TARGET" --format llm
timeout 60s ix subsystems "$TARGET" --explain

For module or file targets:

timeout 60s ix contains "$TARGET" --format llm
timeout 60s ix imports  "$TARGET" --format llm

Full mode:

• raise rank budgets to 20
• inspect the most important systems first, never alphabetically
• for the top systems, collect ix subsystems <system> and ix subsystems <system> --explain

Phase 3 — Behavior

This phase answers how the system works.

Use:

timeout 60s ix explain "$TARGET" --format llm

Also run ix explain for the most important orchestrators, services, or entry points identified in Phase 2.

Behavior budget:

• default mode: explain the top 3-5 important entities
• full mode: for each important subsystem, explain the top 5 classes or services and the top 3 functions or entry points

Optional:

• run one ix trace only if the main execution flow is still unclear after ix explain

Describe:

• request or data lifecycle
• orchestration paths
• subsystem handoffs
• where decisions, transformation, or state changes happen

Do not narrate every edge in a trace.

Phase 4 — Relationships

Map the important dependencies and coupling points.

Use:

timeout 60s ix callers "$TARGET" --limit 20 --format llm
timeout 60s ix callees "$TARGET" --limit 15 --format llm
timeout 60s ix depends "$TARGET" --depth 2 --format llm

If TARGET is the whole repo, do not run repo-level callers or callees. Instead, run these commands for the top-ranked boundary components, orchestrators, or subsystem entry points and summarize the cross-subsystem edges they reveal.

For repo or large system targets, focus on:

• cross-system relationships
• shared infrastructure
• boundary modules
• the most central components from the rank results

When counts are large:

• group callers by subsystem
• summarize repeated patterns
• never list more than 15 similar names individually

Phase 5 — Risk

Always run:

timeout 60s ix impact "$TARGET" --format llm

Full mode:

• also run ix impact for the top 2-5 high-centrality entities

Use this phase to populate:

• fragile integration points
• change-sensitive modules
• shared infrastructure warnings
• parts of the system that need careful testing

Phase 6 — Health

Use:

timeout 60s ix smells --format llm

If the target is smaller than a full repo, scope it when supported:

timeout 60s ix smells --path "$TARGET" --format llm

Prioritize:

• god modules
• highly coupled regions
• orphaned or poorly connected components
• subsystems with weak boundaries

Group health issues by subsystem, not as a flat dump.

Phase 7 — Optional reads

Only read code when graph data is insufficient for an important behavior.

Allowed use cases:

• orchestrators with unclear control flow
• critical entry points on the main execution path
• high-risk components whose role is still ambiguous after ix explain

Use:

timeout 60s ix read <symbol> --format llm

Do not summarize implementation line-by-line. Extract only the behavior needed to clarify the docs.

Writing rules by style

--style narrative

• lead with prose
• each narrative section should explain how to think about the system
• reference layer should stay compressed

--style reference

• still keep the narrative layer first, but tighten it to short paragraphs
• use more headings, bullets, and compact summaries
• make the reference layer more prominent than in narrative mode

--style hybrid

• full narrative layer
• fuller reference layer
• best option for --full, onboarding docs, and handoff docs

---

Output structure

The document should feel like real documentation, not an investigation transcript.

Use this structure.

# [Target] — Documentation

> Generated: [date]
> Scope: [repo | system | subsystem | module | symbol]
> Mode: [standard | full]
> Style: [narrative | reference | hybrid]
> Evidence quality: [strong | partial | weak]
> Coverage: [what was expanded vs summarized]

## Part 1 — Narrative

### 1. Overview
- what the system is
- what it does
- why it exists

### 2. Architecture
- systems -> subsystems -> modules
- boundaries and responsibilities
- high-level structure

### 3. How It Works
- main execution flows
- request or data lifecycle
- orchestration paths

### 4. Key Components
- the most important modules, classes, or services
- why they matter

### 5. Dependencies & Relationships
- major dependencies
- cross-system interactions
- important coupling points

### 6. Risk & Complexity
- high-risk areas
- fragile components
- change sensitivity

### 7. How to Work With This Repo
- where to start
- how to navigate
- common workflows
- what to modify carefully

### 8. Where to Go Deeper
- next files, modules, or symbols to inspect
- suggested exploration paths

## Part 2 — Selective Reference

### Module Summary
For each major module:
- purpose
- responsibilities
- dependencies
- key contained components

### Class / Service Summary
For each important class or service:
- role (orchestrator, boundary, helper, store, adapter, etc.)
- what it manages
- where it is used

### Method Summary
Only in `--full`, and only for key classes or services:
- method name
- 1-2 line role summary
- role in the system, not implementation detail

Reference layer rules

• include only important modules or classes
• if a module is obvious and low-risk, omit it
• if multiple entities share a pattern, summarize the pattern once
• do not add method summaries in default mode unless the user explicitly asks for reference-heavy output

---

Split output

Use split output when:

• --split is passed, or
• FULL=true and the repo is large enough that one doc would become unwieldy

Recommended structure:

<OUT_DIR>/
  index.md
  <system-1>.md
  <system-2>.md
  ...
  <lower-ranked-system>-stub.md

index.md

Should contain:

• overall overview
• top-level architecture
• the most important cross-system flows
• repo navigation guidance
• links to the per-system docs

Per-system docs

Each system doc should contain:

• the full narrative structure
• a selective reference section for that system

Stubs

For lower-ranked systems, create short stubs instead of full docs:

• one-paragraph overview
• top 3 important components
• one risk note
• clear instruction to rerun ix-docs <system> --full if deeper coverage is needed

---

Success criteria

The output is successful if:

• a new engineer can understand the system quickly
• an LLM can reason about the system without rereading dozens of files
• the important parts are obvious
• the main execution flow is understandable
• guidance for deeper exploration is explicit

The output has failed if:

• it reads like a dump
• low-level detail dominates the document
• important components are buried
• every module gets equal treatment
• it gives no practical guidance on where to start

---
